Introduction

This small modification is to adapt two or three buttons to a joystick for ATARI 2600/XL/XE.

Some advantages of this project :

  • More than 70 games are available and growing in the future
  • Only the joystick needs to be modified by adding a resistor for each button added
  • You can buy a ready-to-play joystick
  • Compatible with some SEGA gamepad to use two buttons
  • For developers it can be emulated from Altirra by configuring a custom joystick
  • Modifications of some commercial joysticks are also available
  • A test program is provided for proper testing of all buttons

Hardware changes

The technical details to proceed to perform the modification are documented here

Testing program
